WILLIAM ESBROOK, OF PLAINFIELD, NEW JERSEY.

PORTABLE BUILDING.

SPECIFICATION forming part of Letters Patent No. 638,494, dated December5, 1899.

Application filed July 21, 1897. Serial No. 645,353. (No model.)

To aZZ whom it may concern:-

Be it known that I, WILLIAM E. BROOK, a citizen of the United States,and a resident of Plainfield, in the county of Somerset and State of NewJersey, have invented certain new and useful Improvements in PortableBuildings, ofwhich the followingis a specification.

The present invention relates to that class of portable buildings forwhich I have obtained Letters Patent of the United States under date ofFebruary 16, 1892, No. 468,785. The bolt-clamp E employed in suchpatented construction was so made that it necessitated the initial andpermanent attachment of the clamp to one of the building-sections in themanufacture thereof for transportation. In such prior construction theadjacent section is provided with a bolt having a projecting head, andit could not with such construction be set in place without lifting itto engage such bolt-head with the clamp, and I have found that suchlifting of the section before it could be set in the proper place orsecured to the adjacent section involved considerable inconvenience andcaused delay in the erection of the building. In practice each sectionis furnished with eight couplers, and as such sections are ordinarilywarped and more or less crooked in form the bolts upon the oppositeedges of two sections do not lie in the same straight line, and it isexceedingly difficult and sometimes impossible when one section islifted to engage the should-ers of its bolts with the various slots ofthe couple-rs upon the opposed section. In the present construction Iform the bolt-coupler of a U-shaped loop, having its arms notched uponone side, and can transportthe same separate and independent from thebuildingsections and their bolts, so that the sections may be setdirectly in their appropriate positions and the coupler then applied tothe two bolt-heads simultaneously in the recess between the sections.The sections may thus be delivered and set up in their fixed orpermanent position before applying any of the clamps. The open slot S inthe clamp permits it to slide upon the shoulders or necks of the twoadjacent bolts without any obstruction whether the edges of the sectionsare perfectly straight or not, as the coupling is readily inclined tothe right or left if one of the bolts is not directly above the other.

The invention also includes a means for extending beams through the wallof the portable building and clamping them rigidly to the opposite sidesof such walls. This is effected by forming the beam with a half-lapjoint within the wall, the overlapped ends being provided with shouldersadapted, respectively, to contact with the opposite sides of the wall,and the two parts of the beam being provided with bolts connected by acoupler, so that when drawn together the wall is clamped firmly betweensuch shoulders.

The invention will be understood by reference to the annexed drawings,in which FigureI represents in horizontal section a portion of twoadjoining building-sections.embodying my invention. Fig. II represents avertical section of corresponding parts of the building. Fig. IIIrepresents a partial side view and partial vertical section of ahalf-lap beam-joint for clamping upon the wall of a portable building.Fig. IV is a perspective view of the bolt-coupler. Fig. V is a sideview, and Fig. VI is an edge view, of the coupler. Fig. VII is a planview of part of a wall of the building with a portion of a beam havingthe joint extended through the Wall and having the shoulders upon thebeams formed by cleats L. Fig. VIII represents a modification of theconstruction shown in Fig. VII with the shoulders formed. by reducingthe thickness of the beam at the joint.

The parts of the building-sections 'include vertical joists A,horizontal beams 0, inside and outside boards D, and verticalfillingst-rips B in the space between two sections.

G indicates each oftwo bolts connecting adjacent sections of thebuilding and projected from the beams O in such sections, so that theirheads are adjacent in the recess between the sections when erected. Thebolts are provided with nuts G, fitted into proper sockets of the beamsG, and the heads G2 of the bolts are projected sufficiently from thefaces of the sections to apply the coupler F. Such coupler, as shown inFigs. IV to VI, inclusive, consists of the U-shaped loop, having itsarms notched or cut away upon one side to form an offset F to admit thehead G of one of the bolts between the coupler and the face of theopposed section. The U-shaped coupler is entirely detachable from thenecks of the bolts and may be applied to both of them simultaneouslyafter the sections are set in their proper positions, the turning of thebolt-heads G then serving to draw the bolts into their nuts G, so as toclamp the sections together. The space between the sections is open atits opposite edges while tightening the bolts upon the coupler, and awrench is thus readily applied to the heads of the bolts for suchpurpose, and the fillingstrips B are inserted to inclose such spaceafter the sections are fastened together. The blocks 0 are preferablymade of suitable length to fit between such filling-strips and soadjusted as to set the filling-strips flush with the faces of the boardsD. Such clamping strain tends to bend the vertical joints A, and toresist such strain I insert short blocks 0 between the joists above andbelow the coupler in the space between the fillingstrips B.

In Figs. VII and VIII, L designates a wall of the building, with beamhaving overlapped parts M M, (shown in Fig. 1H,) such parts beingprovided with shoulders to press upon opposite sides of the wall L whenthe parts are drawn together longitudinally by a suitable coupler.

Figs. III and VII show the bolts G and coupler F arranged in theadjacent parts of the beam to draw them together, the nuts G bein gfitted into proper sockets in the beam parts M and M and the heads G2projected to apply the coupler F F.

In Figs. III and VIII the shoulders L are shown formed by reducing thethickness of the beam.

In Fig. VII the shoulders are formed by increasing the thickness of thebeam by adding cleats L. The cleats at the right-hand side of the wallin Fig.VII are fastened to the upper beam M, while the cleats at theleft-hand side are fastened to the lower part M.

Figs. VII and VIII show the beam inverted or in the opposite position tothat represented in Fig. III; but the relation and connection of theparts will be readily understood from the description.

Such construction for the beam-joints operates to frame the buildingtogether in a very rigid manner, while the use of the loose U- shapedcouplers F secures the utmost despatch in the joining of thebuilding-sections together.

I am aware that the first claim in my prior patent for improvements inportable building, No. 468,785, granted February 16, 1892,

includes the combination with the sections of a portable building of abolt attached to one of the sections, a bolt-clamp attached to the otheror adjacent section and constructed with an open slot to receive theshank of the bolt, and a recess to receive the bolt-head or a washerthereunder, substantially as and for the purpose described.

It will be observed that the bolt-clamp which is claimed herein is whenin use attached to one of the sections to admit a bolt attached to theopposed section and that my improved coupler is constructed with an openslot S to receive the shank of the bolt and a recess to receive thebolt-head or washer thereunder, and after my improved coupler is securedto the sections its relation to the parts is similar to that of thepatented coupler.

My first claim herein is merely for the specific construction of thecoupler having the slot S extended the Whole length of the loop, as isclearly shown in Fig. VI of the drawings, and I therefore disclaim theaforesaid patent and acknowledge that the present invention is animprovement upon and tributary to such patent.

Having thus described the invention, what I claim, and desire to secureby Letters Pat ent, is

1. In a portable building having adjacent sections separated by anintervening space or recess, and bolts withheads projected from theedges of all the sections into such recesses, the combination, with eachpair of opposed bolt-heads, of the independent coupler comprising theU-shaped loop F with its arms notched upon one side to form the offsetF, and having the slot S extended throughout its length to admit both ofsuch bolt-heads, whereby the coupler may be applied to both of thebolt-heads simultaneously.

2. The combination,with the wall of a portable building, of the beamhaving lapped ends M, M, extended through the wall from opposite sides,such ends being provided respectively with shoulders adapted to contactwith the opposite sides of the wall, and the two beam ends beingprovided with the bolts G and with a coupler for drawing the lapped endstogether longitudinally, to clamp the shoulders upon the wall,substantially as herein set forth.

Signed at New York city, in the county of New York and State of- NewYork this 20th day of July, A. D. 1897.

WILLIAM E. BROOK.
